Application filed July 28, 1966. Serial 210. 327. 1%.

TER having formally declared his intention to become a citizen of the United States of America, the said ALEXANDER Fosrnn residing at Pasadena. and the said EDWARD it. FOSTER residing at Los Angeles, both in the county of Los Angeles and State of Celiiernie, have invented a new and useiullllethod 0t Constructing a Building and the Apparatus Therefor, of which the following is a. specification.

The object oil our invention is to construct 2i building, and especially the walls thereof that they will he ventilated or provided with an opening from the bottom to the top, and that the oists will be connected therewith in ii strong and substantial manner.

By constructing a wall in accordance with our invention it will have great heat insulating capacity, and can be formed by molding it from plastic material, as cement or corn crete, whereby it can be quickly and cheaply lorined and it will possess great strength with but comparatively small account of i'noterial.

T he accompanying drawings illustrate the invention.

lligure 1 is e vertical transverse section of the well, showing the manner of constructing the lower course of the wall. Fig. 2 is a sirnihir section, showing the manner of constructing the second course. Fig. 3 is uhorizontal Fig. =1 is a. vertical section oi a completed wall. Fig. 5 is e side elevation of e portion cl 9. well. 6 is vertical section of e collapsible mold tube used in the construction. Fig. 7 is c transverse section on the linew -in Fig. 6.

Fig. 8 is a plan of a. wall showing a different form of opening.

ln building the wall a suitable l'ouni'lction or base plate 1 is first constructed and mold hoards 2 are placed on each side thereoi' and held by wires and bracing means 1 toiorni a. vertical trough or channel, A series or plurality of parallel tubes 5 are then placed in this space between the mold boards, the said tubes being of such size as to leave a space between eech tube and the inner and outer mold boards at each side and also to leave a s2 'd tubes are prei'einhl coils isihle, consisting for exampleof :1 split sheet metal tube l 4 provided with inwardly pro ecting lugs e nteach side of the oint and a strip 7, vertically Sl1(l chle in said tu no, and provided with oblique slots 8 to engage said lugs, so that on downward movement of the strip the tube will he expanded, and on the upward niovement of the strip the tube will be collapsed. When the tubes are placed in position hetween the mold or 2, they are in pended condition. nipple or short section of pipe 9 is placed zt'tthe hottoin ol' the well sp ce, extending hetween each tn e 5 and the outer mold hoard. Cement inortsr then placed in the space bet-ween the mold boards and the tubes, forming a. well course with vertical passages 10 therein, coininunicrating at their lower ends by lateral passages 11 with the outer sir.

When the einent has become suiiiciently set, the mold boards are moved upwardly, the wires 3 having been cut and new 'rz ires substituted and are again traced in position as by bracing means 12. The molding tuhes 5 are collapsed and drawn up to or near the top of the formed course and then sgsin expended. it is preferred to only partially withdrew said mold tubes so tl'ist the por tion remaining in the formed tubular pussoge serves as s guide and retainer for the projecting portion oi the tube, as shown in Fig. 12. The cement mortar is then filled into the space intervening between the mold boards and the tubes to form the second course. in o'er, .l. two courses wili carry .the structure to the next iioer shove, the

floor joists indicated st .13 in being then pieced on the wall and the operation proceeding as re until the roof is reached. The tops of the tubular passages 10 he then closed by a. wire gauze screen 1 to exclude vermin and the like and the roofing tiinbers 15 put in place, e'spsce being left over the top of each tubular passage 10 so that en air draft or ventilating e tiOIi upper econ floor J fastened to added cement at intervals. The prei'en ably located beyond the spec-es so to erespace between the successive tubes. The 1 rent the strain or pull. upon there iromthe avoiding joists having a tendency to'split or crack the wall, or pull it apart on the line of the spaces.

The Wall 16 constructed as above described j comprises two portions, an outer portion and inner ortion with intervening webs, these webs ein of less cross section than the cross section of the intervening spaces, thereby not only economizin in amount of material required, but large y cutting off the passage of heat or cold through the wall. The vertically extendin passsages or air spaces being .openat the ottom to the outer air and at the top to the interior of the house or attic, it follows that there will be in general. a circulation of air therethrough with the result that the wall is kept dry, thus the clamminess or coldness and dampness generally found with cement walls. The fact that the vertical passages in the Wall are round insures maximum strength of the construction for a given Weight, each web portion flaring or expanding toward each outer wall portion so as to brace every part of such outer wall portion and obviate any extended thin portions which would be a source of weakness in the wall. The same result can be obtained by forming the wall with polygonal holes as indicated at 17 in Fig. 8. It will be understoodthat the term cement mortar herein used includes any structural material suitable for application in the manner by molding, for example, magnesite, 'as well as ordinary cement. What we claim is The method of constructing a building, which consists in placin mo (1 g each side of the s ace to e occu ied by the respective walls oi the building, then placing elongated members vertically between the 40 boards at a distance from each other and from said boards, then lacing a space forming member between t e lower end of each vertical member and oneof said boards, then fillin a cement mortar in between said elon-' gated members and boards, then, after the cement has hardened, removing said boards and members, then successively securing said boards to the upper edges of the portion of the wall already formed, and re lacing said elongated members as before and again filling in said spaces with cement until the wall has been completed, and at certain desired points in said wall and between the vertical members embeddingbeams and the ends of the joists in the cement and connecting them by means of ties, said beams being beyond said spaces, then covering the upper ends of the spaces formed by the vertical members with wire gauze, and, finally, placing the roof in position and finishingthe uilding.-

In testimony whereof, we have hereunto set our hands at Los Angeles Californiathis 9th day of July .1906.
